Installing an IDE CD-ROM It is recommended that the IDE CD-ROM drive be connected to the CD-ROM data cable rather than to the HDD data cable. Connecting the CD-ROM drive to the HDD data cable can reduce the performance of the hard disk drive connected to it. The CD-ROM data cable has a red connector and is marked "CD-ROM" next to the system board connector. 21-4 HP Vectra VE 5/xx Series 2 PC Medium-Profile Desktop Vectras
